or is formed on its active face with a tapered upper surface below which the surface is verv- ,tical (ile, parallel tothe axis of the station 9 lever above described, but'the equivalent of ary rod), while rearwardly of said surfaces the rod end iron proper is constructed with a Vertical rack with which there engages a pinion carried by an arborsupported in a bearing formed in a depending extension of the aforesaid first mentioned bracketv or slide.

This arbor, upon which is also keyed a cam, extends forwardly of the frame and is fitted with a handwheel. h

At or near its rear bottom end the rod end iron proper has an integral right angled projection below whi'ch is mounted a cushioning spring heldin position by a verticalstem. Actuatively' connected to said pinion is a clock spring, and a detent pivoted to said bracket or slide is adapted to engage with the cam on the pinion shaft, the free end of said detent being attached to awire or analogous flexible control leading therefrom to the aforesaid delivery regulator.

-This delivery regulator is preferably mounted adjacent one end of the lower front roller spindle which isextended through the 1 frame end into acasing or bracket attached thereto and has formed on it. or carries a worm engaging with a worm wheel keyed upon a spindle supported in a bearing formed in the aforesaid casing or bracket. A stud projecting from the casing or bracket, below said sp1ndle,carr1es an angularly movable lever whereof the lower end is connected by a wire, or analogous flexible connectiornto the aforesaid; detent' engaging the cam on the rod end iron assembly, while the upper end of said angularlymovable lever is disposed in the path of movement of a stud carrledby I said worm wheel.

On the worm wheel spindle, outside said casing, is loosely mounted a disc whereof the outer face is graduated in terms of yards, said disc also being apertured to engage a pin or studprojecting into said casing or bracket;

I and, also on said worm wheel spindle there are mounted, a pointer whlch is movable over the subdivided face of said disc, and a knurled nut to clamp the pointer in a selected position.

The worm wheel spindle is movable axially in its bearing and-is provided with a concen-;

trically arranged return spring located between the worm wheel and the bearing.

This delivery regulator, it will thus be seen, co-operates actuatively with the'front rollers of the frame and also with the rod end iron assembly.

In the application eras invention to a frame of the-cap or the flyer type, there are certain constructional differences.

The short lever of the builder motion isnot extended-and does not carry the slotted such slotted lever is constituted by a bent lever'carried pivotally by a vertically slidable'raok member forming part ofthe rod end iron assembly,which bent lever'carries a rolleradapted to engage a-stationary inclined stop or plate fixed to the upper rail of the frame; said lever being movable angularly to cont-act with a rounded lug (the equivalent of the roller for action during the bunch pick previously described) formed on the end of the chain rod which also carries a second rounded lug for action during spinning by contact with an adjustable stop or screw taking into a lug on the rod end iron at its forward upper end.

The aforesaid vertically slidable rack member is supported by a stationary rod carried by lugs projecting from the rod end iron, and

the rack engages a pinion mounted on an arbor carried by the rod end iron to which arbor is anchored a clock spring as before. A cam is also keyed upon said arbor and is .en-

gaged by a detent connected by a wire or like ness.

The pin 55 prevents rotation of the disc 54 while the aforesaid. adjustment is being made. The frame is then started up and the Wormwheel 49. is rotated until the wrist pin 53 trips the extension 41A of lever ll and moves lever 41 angularly, and thus through the cable 37 actuates the latch or detent 36 when the predetermined number of yards of yarn for the bunch have been delivered by the front rollers. I The worm wheel 49 continues to rotate a little further and is brought to rest by the gap 49A disengaging it from the worm Still referring to the application of the invention to a ring spinning frame, and assuming that empty bobbins have been placed upon .the s indle s 8 and the rin rail 7 has been brought to the starting position by means of the usual handwheel 18D, preparation for building the bunch is made first by setting the delivery regulator as just described, and then by rotating the handwheel 31 so as to cause the pinion 24: through rack 23 to lower the slide or rod end iron proper 22 until by the re .tion of the cam 32 the latch ordetent 36 engages with the nose thereof when the bunch building roller on the chain rod 9 will be in contact with 111 Figure l.

the slotted lever llas shown The frame ,is then set in motion throu h the usual means and, through can lt the short lever 13 of the builder motion is oscillated and with it the extension 13A located above the'pivotal axis 13B of the lever which has the I slotted connection with the lever 11.

- The arrangement of this linkage is such that a shorter nick than is normall the case is imparted to the chain rod 9, this length'of piclrbeing h tan inch. for the duration of bunch building.

dVhen the predetermined length of yarn has been wrapped on to the bunch, the above 9 tact lon itudinall intothe sainnin osition as soon asthe parallel face of slide 22 engages roller 26, and remove. the roller'flO fromconiii the lever ll, shown in Figure 3. The r iioning" spring 33A supplements the site of theclock spring 35 in raisingthe )arts.

The whole of the rod end iron assembly now reciprocatesand conveys motion from the cam 14 to the roller 20 thus imparting the normal pick to the chain rod 9 for the duration of the spool building- :Referring now to Figures 7, 8', 9 and 10.

The spindles 8A are fitted with caps 8B and the lifter rail 7 B is carried by the lifter spindles 7C. The short lever 13 of the builder motion is of normal construction, that is to say, it is not extended upwardly above its pivotal axis as in the case of a ring frame, nor does it carry a slotted lever, but the equivalent of the lever 11 is constituted by the bent lever 58 mounted pivotally at 58A upon a vertically slidable rack member 59,

said lever 58 carrying a roller 60 which is adapted to engage a stationary inclined stop plate 61 fixed to the spindle rail 6.

The chain'rod 9 has a plate 62 bolted at 62A, 62A, to it, which plate is formed integrallywith a boss 62B holding a pin 62C passing through a fixed guide eye 62D to prevent tilting of the chain rod 9.

Said plate 62 is also formed integrally with a rounded lug 63 .(the equivalent of the aforesaid roller 10) and with a second rounded lug 64 (the equivalent of the roller 20) the lug being contacted with during bunch building by the bent lever 58, and the lug 64; being contacted with during spool building by an adjustable stop 65' taking into alug 65A formed on the slide orrrod end iron 66.

, The rack slide 59 is carried by the rod end iron 66 which is formed integrally with two lugs 66A, 66A, supporting a stationary ver' tical rod 67 on which the slide 59 ismounted by means of a boss 59A. The rod end'iron 66 is also formedwithbearing bosses 66B and 660, the former boss 6613 for a spindle 68 on the forward or outer end of which is a handwhe'el 69, and the latter boss 66C for an arbor 70 which extends through the part 66 and has keyed on its inner end a gear wheel 71 meshing with a pinion 72 keyed on the inner end of the spindle 68. On theouter or forward end of the arbor 7 O is secured one end of the clock spring 35 whereof the outer end is secured to a pin 35Aheld in two ears 66D, 66D, integral with the bearing boss 6613. Near the centre of its length the arbor 70 also haskeyed on it a pinion 70A I 73 with which engages a latch or detent 74 pivoted at 74A and having attached to it the control wire or cable 37 connecting it with the dellvery regulator as in the previous construction. I

In the embodiment of the invention, just described, as applicable to a cap or a fiyer frame, preparation for buildingthe bunch is made first by setting the delivery regulator in the manner explained with reference to Figures 5 and 6. The handwheel 69 is .then rotated and, by means of gearing 70A, 71 and 72 the rack slide 59 is raised until the roller 60 has contacted with and ridden over the inclined surface of stop plate 61 into the position it is shown'to have reached in Figure 7. By this elevationof rack slide 59 the cam 73 is caused to rotate and to secure engagement with the latch or' er motion) the p1ck reducing lever 58 is oscillated and imparts through lug 63 the requi site short pick to the chain rod 9 for the du- V ration of the bunch building.

I When the requisite lengthot yarn (previously set up on the disc 54) has been wrapped on to the bunch, the deliveryregulator operates, exactly as before, to withdraw the latch or detent 7 4: from engagement with the cam 73 whereupon the spring actuates pinion 7 OA'and causes the rack slide 59'to descend into the position shown in Figure 9 wherein the nose of the bent lever 58 has been building lug in a manner analogous to the lever 11 withdrawn from contact with the bunch 63 and, owing to the weight of the lifter rail and associated parts, the chain rod has received longitudinal movement to the left by an amount'sulficient to bring the spool building lug 64; into contact with the stop 65 carried by the rod end iron 66, whereupon spool building continues in the normal manner until the spools or bobbins are completed. o i a v During the normal building of the spools the rod end iron 66 is moved, by the builder motion, the full travelof say, two inches, but during bunch building this extent of travel becomesreduced to, say, half an inch, by reason of the roller 60 becoming the fulcrum of the lever 58 which thereby functions of Figure 1. V y

It is to'be observed that in Figurel of the drawings the builder motion cam is shown as having come to rest with a re-entrant portion in contact with the roller on the short 7 a lever.

with a salient portlon or peak in contact with If however the cam hadcome to rest the roller, the position of the ring rail would be higher than that illustrated. Conversely,

: in Figure 7 of the drawings, the builder motion cam has come to rest -Wltl1tl16 salient or peak in'contact with the roller on the short lever, but it it had stopped with the reentrant engaging would have been positioned lowe'r'than as il-' lustrated in Figure 7,

It is, however, immaterial :whether when the frame is stoppedthe builder motion cam is in the p'ositlon illustrated, or that justreferred to, or in any intermediate position, the

the roller the lifter rail' reducing lever on position in which the-lifter motion comes to rest.

r It therefore becomes manifest that, by the ltwo con'structional forms of the invention just described,'the position of the bunch on the spool isdefinitely determined ,the amount of yarn 'wrapp'edon to the bunch is positively regulated to"apredetermined length, and for bunch building the normal pick is reduced tor the duration o1":- the bunch and, 011.com
